Patch

This shareable config uses rules from external plugins such as eslint-plugin-prettier. This patch improves how ESLint loads plugins when working for example in a monorepo, see: https://github.com/eslint/eslint/issues/3458

.eslintrc.js

// Patch ESLint module resolution to find shared configs' plugins
require('eslint-config-fmal/patch/modern-module-resolution');
